Program crashed

I have written a program that when I quit the program using an administrator ... would stop responding and I have to manually end task ... However, when I run the program as limited account ( windows xp ) the program works prefectly ... ( The program save the configuraion when it quits and it unload itself from the task bar )

Do you guys have any idea why this happens ?( it doesn't matter if I make an executable or run in visual basic ... it would crash ... )
